Stress resistance enhancing with biochar application and promotion on crop growth

Biochar, Journal Year: 2024, Volume and Issue: 6(1)

Published: May 6, 2024

Abstract Environmental stressors such as drought, salinity, and heavy metals pose significant obstacles to achieving sustainable food security, necessitating the development of universally applicable cost-effective solutions ameliorate soil under stress. Biochar, an eco-friendly material increase crop yield, has been researched for almost two decades great potential global use in enhancing stress resistance. However, there hasn't comprehensive research on impact biochar application properties, root growth. To optimize promote agriculture stress, this study integrates over 100 peer-reviewed articles explain how promotes growth by resistance Biochar's distinctive porous structure, alkaline nature, enriched surface functional groups, nutrient content, are responsible following environment benefits: improved physiochemical increased cycling, boosted microbial Moreover, emphasizes that enhanced optimizes absorption, alleviates pollutants, thereby enhances overall productivity. The discusses roles mechanisms well challenges linked economical implementation extreme conditions. This review aims provide a theoretical basis widespread improving stresses, health security.

Sludge-based biochar preparation: pyrolysis and co-pyrolysis methods, improvements, and environmental applications

Fuel, Journal Year: 2024, Volume and Issue: 373, P. 132265 - 132265

Published: June 28, 2024

The pyrolysis of sewage sludge to produce biochar is a promising method for end-treatment. Key parameters influencing properties include temperature, heat transfer rate, residence time, additives, and raw material types. Sludge-based (SBC) features porous structure, aromatic compound composition, high absorbency, stable chemical properties, large specific surface area, numerous functional groups, making it suitable environmental applications such as soil remediation water quality improvement. However, SBC alone can pose risk due excessive heavy metal content. Co-pyrolysis biomass with has been shown mitigate this by fixing metals reducing their accumulation in biochar. Research indicates that co-pyrolysis produces superior including larger better pore more greater pollutant adsorption capacity compared alone. Thus, sludge-biomass significant potential overcome the limitations single sludge-based biochar, facilitating large-scale production application management.

Biochar produced from waste‐based feedstocks: Mechanisms, affecting factors, economy, utilization, challenges, and prospects

GCB Bioenergy, Journal Year: 2024, Volume and Issue: 16(8)

Published: July 8, 2024

Abstract Biochar possesses unique characteristics, including a substantial surface area, high carbon content, sufficient capacity for cation exchange, and robust structure. However, biochar contains hazardous pollutants like volatile organic compounds that harm soil properties functionality. Although several studies on production from various feedstocks have been undertaken in recent years, issues about feedstock preparation, economic feasibility, influencing factors, the proper utilization of processes need to be addressed. This paper thus addresses these by providing potential solutions identified through comprehensive review. Slow pyrolysis lignocellulosic biomass Acacia nilotica yields 20 52 wt% at temperatures residence times. yield varies 29 48.3 when waste tires corn stalks are rapidly pyrolyzed higher shorter periods. Torrefaction algal moderate with different times can result 50–60 wt%. variability heterogeneity pose challenges affecting biochar's quality properties. Given its widespread use sequestration, remediation, wastewater purification, composting, mechanisms environmental usage investigated.
